有限差分，分析激光器内载流子浓度的分布。激光器有源区的自发发射光谱(Finite difference analysis of lasers with carrier concentration distribution. Laser active region of the spontaneous emission spectrum)

这个程序是用MATLAB编的，是用迭代法实现图像的分割，得到感兴趣区域。(This program is retained by MATLAB，and it uses Iterative method to implement image segmentation and obtain the region of interest。)

对调制信号的频谱进行估计，通过多径和高斯白噪声的信道，解调信号的频谱和输入信号相比较(Spectrum of the modulation signal is estimated by multi-path and Gaussian white noise channel, the demodulated signal of the spectrum and compare the input signal)

详细的Total Commander帮助文档，可以帮助使用者迅速上手入门(Detailed Total Commander help document, can help users get up and running quickly entry)

本帖调用自编函数（grating）绘制光栅条纹图像，通过例子讲解水平、竖直、环状和辐射状光栅条纹图像的绘制，用黑白和彩色显示效果给大家视觉上的震撼。调用自编函数时，可以通过成对出现的参数控制条纹的方向、颜色、周期、相位角等。(This post calls self-function (grating) draw grating image, by way of example to explain the horizontal, vertical, circular and radial grating image rendering, with monochrome and color display give you visual shock. Self function call, the parameters can be controlled by pairs stripe orientation, color, period, phase angle.)
